Riyadh--Hadi had laid out his government's demands in a pre-talks letter to UN Secretary General Ban Ki-moon, insisting that the rebels must withdraw from territory they have seized.
He reiterated his position on Sunday during talks in Riyadh with Ban's special envoy, Ismail Ould Cheikh Ahmed.
In a bid to restore Hadi's authority, Saudi Arabia has led an air campaign against the Huthis since March 26.
Coalition aircraft bombarded targets across the country at the weekend, including the airport in second city Aden and its northern suburbs, officials said.
On Monday, residents and an official in Taez said fierce fighting had killed and wounded dozens of people.
The clashes, which erupted on Sunday and raged overnight, have killed at least 30 Huthi rebels and allied forces, the official told AFP.
He said a provisional toll showed at least five Hadi loyalists were also killed.
For a second consecutive day, rebels and their allies targeted several Taez neighbourhoods with rockets and tank shells, residents said.
Medics and residents told AFP late Sunday the bombardment had killed 10 civilians and wounded 80.
Officials in neighbouring Daleh province said pro-Hadi fighters had retaken several positions from the rebels, including a military camp, in dawn fighting on Monday.
